I don't remember exactly how, but I think TWRP ended up corrupting some of my phone. Regardless, now when I try booting into a recovery other than the CM14 Recovery, I just get a black screen after the OnePlus logo and nothing happens. I have had other problems too, like CM Bug Report Has Stopped every startup and app (un)install. I can also install CM14, which I've done multiple times, but stock OxygenOS will not work, and neither will Open GApps. When I sideload these zips it seems to stop midway anyway.
Just for information, my bootloader is unlocked, I currently have CyanogenMod version 14.1-20161119-NIGHTLY-oneplus3 installed, and I tried using MultiROM before (probably the cause, and I probably won't use it again) mostly as an easy backup/ROM switching system as my main ROM didn't like the MultiROM boot addition.
In an attempt to restore full functionality, I have tried all of the wiping options the CM recovery offers, including formatting the userdata partition when it couldn't just wipe it (happened the first time). I also tried the MEGA Unbrick guide, which seemed to have incomplete instructions (or something), but in essence I used fastboot to flash the full .rar file reformatted as a .zip file. This just resulted in a black screen for both the main system and the recovery, so I've given up. Is there a way to restore my OnePlus 3 to its former glory?
Also, I had a TWRP backup, which not only could I not use but it got deleted after wiping /data, but I do have adb backups (stored on a computer) of everything that I could back up.
Below is pasted a log (/cache/recovery/last_log) from trying to install Open GApps:
